Curl for northerly star charts

I have added chart data files such as hygxyz_northofminus40_ucs.csv through hygxyz_northofminus10_ucs.csv and a hygxyz_north_only_ucs.csv at URL's such as

http://www.aule-browser.com/astro/stars/hygxyz_northofminus40_ucs.csv

for which the row counts vary from  93,132 down to 58,767 CVS data rows with the top 2 rows the usual info-only. The files are comma-separated fields of variable length encoded as utf-8.

Curl for star charts

As prep for building MIT/SCSK Curl 2-D path star charts, I have stripped the hygxyz.cvs file to 100K rows for the stars North of -50 Dec.  Please excuse my northern hemisphere bias.

I have made these CVS HipparcosYale+ files avail at  http://www.aule-browser.com/astro/stars/hygxyz_northofminus50.csv with alternates in three parts as hygxyz_PART_1_northofSouth50.csv and hygxyz_PART_2_northofSouth50.csv etc.

For UTF-8 versions of any of these files, add _ucs before the .cvs extension.

Please let me know if you see issues.

The regex used to drop rows was:

^[0-9]+,[0-9]+,([0-9]+,|,)([0-9]+,|,)([A-Za-z0-9\s^,]+,|,)([A-Za-z0-9\s^,]+,|,)[0-9]+\.[A-Za-z0-9^,]+,-[5-8][0-9][\.].*$

The CVS header is

StarID,HIP,HD,HR,Gliese,BayerFlamsteed,ProperName,RA,Dec,Distance,PMRA,PMDec,RV,Mag,AbsMag,Spectrum,ColorIndex,X,Y,Z,VX,VY,VZ
